Split 2 csv files into smaller sets of files based on unique values in python

Question

Sorry if this question has been asked before, I just couldn't find a simple example.

I have 2 large CSV files that I would like to split based on the unique values in the Location & LocationType Column. I would like to store the split csv files into sub-directories for each value in a folder named item/{item_name} where item_name is the unique value in Location & Location_type.

• Location.csv

• Location-type.csv

• Each split csv file should have the same header line as the parent file
• If the sub-directory already exists, delete those files before writing the new files.

End result would be a directory called item with two sub-directories called fm5 & fm15 with our split CSV files stored. location.csv & location_type.csv

Thank you in advance

Answer 1

would like to know the workflow for this type of project

• open the file
• sort the contents on the desired column
• group by the desired column
• write each group to a new file
